Information processing method, presentation method, program, and manufacturing method

A presentation method for thermal fluid analysis, executed by a computer system, comprising:

• receiving input of one or more chemical formulas of respective one or more molecules constituting a substance and a composition ratio of the one or more molecules;
• generating an image indicating continuous data for each physical property value required for thermal fluid analysis based on the one or more chemical formulas and the composition ratio which are input;
• and
• presenting the image generated.

A manufacturing method for physical property change data of a substance, executed by a computer system, comprising:

• acquiring one or more chemical formulas of respective one or more molecules constituting a substance and a composition ratio of the one or more molecules;
• determining, from the one or more chemical formulas of the respective one or more molecules, one or more molecular feature values of the respective one or more molecules;
• and
• generating physical property change data representing a change in a physical property value of the substance by using the composition ratio and the one or more molecular feature values.
